I was under the impression that when you try to write another byte that the
voltage would drop. I have never used frobbing but I thought that if you
frobbed that only the specific pins that needed to change would do so, while
the ones not needing to change would maintain voltage.
"Maybe I read the wrong fictional novel?"
